1. Narrative: Such a style is associated with content flowing in a sequential order. It is usually written in the first person and is a personal account of an individual. It may or may not bring out a theme or central idea.
2. Descriptive: This merely involves a detailed description of all things, materialistic as well as non-materialistic. This is usually indicated by the use of the various senses- how the subject of the passage feels, what he can smell, see, taste and hear. The experience or object described may have been positive or negative.
3. Dialogue-oriented: This style is the one where the content is more like a story and less informative. This usually includes characters that are linked to each other by a common thread and converse using direct speech.
4. Argumentative: This kind of a composition is the easiest to identify. It involves the author taking a particular stand and justifying his opinion through various instances. As such, only one side of the argument, either in agreement or disagreement, is shown.
5. Reflective: This is much like an argumentative composition. However, it presents both the sides of an argument and its tone is almost neutral or only slightly biased. It is a well thought-out piece of work.
6. Analytical: As the name suggests, it involves magnifying of a small topic and an in-depth analysis of the same. Amplification of points regarding the central topic is the key to identifying such a style. It involves reasons, logic and a proper conclusion.
7. Critical: This is usually like a review of a particular book, movie, piece of art, etc. It points out the exact nuances that work for or against the object. It is an honest opinion given by the author.
